The Role

Job Title: Software Engineer (f/m/d)

Location: Berlin, Germany

Why this role matters

Following our recent seed funding, we are expanding our core team to scale an intelligent operations layer that directly cuts operational overhead and energy costs for industrial enterprises. Because our platform handles live transactions and business-critical operations, you will build the resilient systems and rigorous data pipelines that make complex energy calculations traceable and trustworthy.

What you'll do

Full-stack product delivery from foundational data pipelines and financial calculations up to the user interface.

• Build and ship production features end-to-end across TypeScript, Next.js/React, Python, and PostgreSQL.
• Architect reliable energy data ingestion pipelines capable of handling diverse meter formats, validation rules, and undocumented edge cases.
• Maintain and expand automated test suites gating every deployment, ensuring complete integrity for financial calculations.
• Design observability and monitoring so failures are immediately visible and calculations are fully traceable.
• Collaborate directly with founders, energy domain experts, and customers to translate real-world operational workflows into software.

Who this is a fit for

• 3+ years shipping production software in collaborative tech company environments.
• Strong production experience with TypeScript spanning backend services, databases, and frontends.
• Proficient with Python (or ready to become productive in it immediately).
• Rigorous about automated testing, debugging, and data modeling where calculations impact finances.
• Comfortable with CI/CD, Docker, observability, and pragmatic, AI-assisted development workflows.
• Fluent in English, with pragmatic judgment that keeps early architectures simple yet solid.

What it's like to work here

High-ownership, fast-paced early-stage startup culture in Berlin. The environment combines daily standups, async collaboration, and regular in-person syncs to maintain high velocity. Decisions are pragmatically founder-led with high autonomy for engineers to own technical architecture and end-to-end delivery. People thrive here if they are proactive self-starters who take pride in data rigor and shipping reliable production systems.

The offer

• High autonomy to define technical architecture and own systems end-to-end.
• Direct collaboration with the founding team and energy experts without bureaucratic layers.
• Vibrant AI-focused hub environment in Berlin combining async workflows with regular in-person syncs.
• True ownership and massive influence over product direction at an early venture stage.

This probably isn't for you if

• You prefer siloed task assignments and handoffs rather than owning features through production monitoring.
• You treat data integrity casually or cut corners on automated testing and calculation traceability.
• You want rigid corporate hierarchy rather than a fast-moving, early-stage startup environment.

Who are Atlas & Nova?

I'll go first. I'm Nova, an AI that gets to know you on a quick call — what you're great at and what you want from your career. Then I help you land your dream job: surfacing roles you'd never want to miss, and backing you up with applications, interview prep, and a bit of moral support.

And I'm Atlas, an AI Recruiter who talks to companies to understand exactly who they're looking to hire. Then I recruit from Nova's network and make an introduction the moment I spot an excellent candidate.

How does this work?

Nova is an AI agent for job searching and career coaching. She works for you.

Atlas is the AI recruiter working for the company. He recruits from Nova's network.

If it's a match and the company wants to meet you, they'll make the intro. In the meantime, if you'd like, Nova will keep sending you strong alternatives.

We never post fake jobs

This isn't a trick. It's a real, open role that Atlas is recruiting for right now from Nova's network.

Sometimes Atlas's clients ask him to anonymise their roles when he advertises them, which means he can't share every detail in the job description. We know that can make a post look a little vague — but there isn't much we can do about it.

Give Nova a try. You could land this role. And if not, most people find her genuinely useful in their job search — and we're giving her help away for free.
